Exhaust Questions - Cat Delete & Exhaust Temperature Sensor?
 

Hi Guys,

I'm hoping to install a Fabspeed cat-bypass downpipe and cat-back over the winter. The car is otherwise stock, so what do I do with oxy sensor? Looks like the Fabspeed setup does not have a bung welded in to place the oxy sensor. Should I just weld one in myself?

The oxygen sensor is actually in the crossover up pipe (turbo inlet). So you would not be replacing that with the FabSpeed cat-bypass.

You are totally correct, my bad, noob mistake.

I have another sensor about halfway down the exhaust system, PET calls it a temperature sensor and it is marked as (J) for Japan only. My car was imported to Canada from Japan.

Any idea if this sensor actually influences the running condition of the car, or does it only trigger a warning light?
